调研方向

首先查看 Arc.Config、DAO 和 DAO.Data 中描述的组件订阅行为,尤其是 DAO 状态更新如何触发重新渲染。在决定是否推进优化之前,先收集提议的指标;完成的标准是确定一个经过测量且达成共识的范围,仅重新渲染与 DAO 连接的组件。

由索引模型根据 Issue 内容生成。

描述

hi-pri perf-enhancement

Only rerender components that are "DAO Connected".

This can be done through supporting a subscription model, where components that depend on additional contextual information (ex: , ).

For example, consider...

<Arc config={new Config("web3provider", "graphqlprovider")}>
  <View1 />
  <DAO address={"0x1234"}>
    <View2 />
    <DAO.Data>
      {data => (
        <View3 value={data.value} />
      )}
    </DAO.Data>
  </DAO>
</Arc>

Ideally, if Arc.Config's web3 provider changes, View1 & 2 shouldn't have to rerender, but View3 should because the data may be different. This can be partially achieved if DAO connect's the Arc.Config's subscriber list, which will cause it to be told to rerender if the config ever changes, but this only causes View1 to not be rendered. View2 would still be rendered because currently the data is stored within the Component's state (the DAO's state), which would cause View2 to still be rendered.

Going to leave this here for now, as it'll be interesting to come back to this after some metrics have been gathered, as I feel this may be premature optimization.
